Default adding oxygen to resirvor

hi ron, so i have a question when you add a air stone to the res ,does it only come on when the flood pump comes on ? if so i have built my system with a inline venturi air injector ,that puts air into the water line as it is filling the the system(flood&drain),this takes no electricity and seems to be working (only been set up for 2 days). it took a little time to figure out the proper flow rate of water(pump size) and orifice size to get air injected,but i can see the micro bubbles in the jugs as they are filling!!
let me know what you think,andy
